Chapter 422

Two tusks can easily pierce the neck of the prey and instantly kill it.

However, the female's mouth has no jaw, and it is about to degenerate completely. The male is also degenerating. Since the brain began to develop and evolve, the more and more intelligent of them do not seem to be as fierce as their ancestors.

From birth to 133.57 million years later, this species learned to make tools, and tribal civilization was born, which started the journey of conquering the earth.

After 133.63 million years, that is, about 680 million years ago, this species has entered the era of nuclear civilization, and created a more brilliant amphibious civilization on earth than human beings. There are their cities on land and their cities in the water.

However, even if they did not find the origin of the purple crystal in the moon, they did not find the origin of the purple crystal in the moon.

This civilization has dominated the earth for more than 130 million years. They have gone through the most dangerous period, and even stepped into the level of star civilization. This civilization has been able to easily resolve the threat from the universe, especially the threat of asteroid impact on the earth. At the most glorious moment of its civilization, an asteroid with a diameter of 30 km collided with the earth Before being successfully resolved.

However, even if their civilization has been so prosperous and powerful that it is beyond the reach of today's planetary civilization, there is still power that they cannot resist.

When Ren Hong saw this, he found that there was a star that had disappeared more than 600 million years ago in the star region around the solar system.

More than 600 million years ago, that is, the era of prehistoric civilization, there were 12 stars in the universe 11 light-years away from the solar system, but only 11 stars exist today. They are four single star systems: "Barnard star", "wolf 359 star", "Roth 154 star" and "Leyland 21185 star"; two double star systems: "Sirius a" "Sirius B" and "luyton 726-8a", "luyton 726-8b"; a three-star system: "alpha Centaurus", "beta Centaurus" and "neighboring stars".

In the universe more than 600 million years ago, there was a fifth single star system 11.7 light-years away from the solar system. The star was born 1.25 billion years ago, when this species did not exist on earth. At that time, the star was ten times brighter in Earth's night sky than Sirius, and was pale blue in the night sky.

Since its birth, this star has been unknown, but it has been burning in glory for nearly 700 million years. Although the star has a "constant" character, it is not eternal. The star also has a life span. The volume of this star is 53 times that of the sun, and its life is not expected to exceed 1 billion years.

In fact, 700 million years of time will finally burn out its life. The hydrogen element responsible for fusion fuel is less and less. The helium formed by fusion is deposited to the center by the gravity of the star. More and more helium materials are gathered in the center, and the remaining hydrogen is still in fusion, like the last breath of life.

Finally, helium fusion took place, but the fusion of helium produced far less energy than hydrogen fusion reaction, and the star's gravity continued to shrink, rising temperatures almost never-ending.

The beginning of helium combustion means that light elements will fuse into heavy elements, which means that the star will eventually explode.

In this glorious period of the earth's integrity, the intellectual civilization has found this star in its old age.

The luck that lasted more than 130 million years is finally coming to an end.

It is only 11.7 light-years away from the solar system. Its death will affect the whole solar system and the space of more than ten stars around it.

And civilization on earth can't stop it. When that star explodes, it means death and extinction. This civilization, at its most glorious moment, is accompanied by the crisis of genocide at any time.

They know that the star has entered its old age. It has been burning for 700 million years, and it may explode at any time. It may be tomorrow, maybe 100 years later, maybe 10000 years later, maybe a million years later, or even 11 years ago. We should know that it takes 11 years for light to travel back to earth from there, and all we see is what we saw 11 years ago.

They can stop an asteroid from threatening their homeland, but they can't resist that star's fury, and it could explode at any time.

The only hope to survive is to leave home, out of the solar system.

However, even in its heyday, this civilization is still unable to stay away from the solar system. They have just entered the stellar civilization. The largest activity area is limited to the solar system. Without the restriction of breaking through the speed, they will never be able to enter the stage of Galaxy civilization. The speed limits them.

But they didn't wait to die. In order to avoid destruction in the future, they decided to leave their home and drift to the Unknown Universe. The people who built the space station first, and then put the whole solar system out of their power. However, there is only one outcome for more clansmen waiting for their fate. In limited time, they can not move the entire civilization out of the solar system. In order to deal with the stars that may explode at any time, their space station does not take too much time to build. For the sake of population continuation, if you can leave quickly, you will never look back. Because the speed is not faster than the speed of light, you can only use time to make up for it 。In this way, 68 years later, they have been fleeing out of the solar system in order to continue the fire of the population.

In the 55th year of the race escape, stars as far as 11.7 light-years away have finally come to the end of their lives. The gravitational force produced by the huge body of the stars produces repulsive reactions. The density of the core is so high that it is unimaginable that the matter of a grain of rice in the core weighs billions of tons.

The dense core finally broke through the limit of the critical point and collapsed, and the whole star collapsed instantaneously from the inside out.

At the moment of star explosion, the whole universe seems to have been torn apart. At the last moment, it ended its life of 700 million years in the most powerful form. The huge and dense debris, endless dust, electromagnetic pulse with nearly infinite energy, high-energy particle flow, sub radiation flood and other lethal substances rush around the universe at the speed of light A corner.

This accumulated 700 million years of "anger" is also moving towards the solar system 11.7 light-years away. It will arrive in the solar system 11.7 years later. Whether it is the earth, Mars, Jupiter, Saturn, the whole solar system will be unable to avoid the impact of this accumulated 700 million years of "anger". For the life in the solar system, this is irresistible, hopeless and destructive.
